Abstract
The utility model provides an instrument for determining a spheronization index of iron concentrate powder. The instrument is characterized in that a cushion block with the very strong water-absorbing capability is placed in a water containing container; a charging device in a metal pipe shape is placed on the cushion block; the upper opening of the charging device is a through hole and the bottom of the lower opening of the charging device is sealed by a hole plate made of an organic glass thin sheet; small holes with the diameter of 3mm are uniformly distributed on the hole plate in a distance of 4mm; a piece of cylindrical pressing iron is further placed in a pipe-shaped metal sleeve; the pressing iron can move freely in the sleeve. The instrument provided by the utility model has the advantages that the spheronization index of the iron concentrate powder can be calculated by simply, rapidly and accurately determining the data of maximum molecular water and capillary water of the iron concentrate powder, so as to take an active guidance effect on the generation of pellets.
Description
Affiliated field
The utility model relates to a kind of steel and looks forward to the instrument that sintering plant is measured the iron powder data, especially adapts to the instrument of measuring iron essence balling-up sex index.
Technical background
The iron fine powder is the primary raw material of steel enterprise sintering plant, research to iron fine powder balling property is the front topic that improves the pellet quantity and quality, and the balling property of evaluation iron fine powder need be measured maximum molecular water and the capillary water of iron fine powder, according to measurement result, according to formula, calculate, the balling-up sex index value of the fine powder of must tapping a blast furnace, be used to instructing pelletizing production.Steel is looked forward to the pelletizing production raw material mix complexity of sintering plant at present, the iron fine powder balling property difference of different cultivars is large, sintering plant testing laboratory is again without the accurate specialized equipment of measuring this numerical value, aspect research to iron fine powder balling property, be a blank, during production, the workman can only judge numerical value by rule of thumb all the time.With the maximum molecular water of simple and easy, quick, Accurate Determining iron fine powder and the data calculating of the capillary water fine powder balling-up sex index of tapping a blast furnace, it is problem anxious to be resolved.
Summary of the invention
The purpose of this utility model is: design the tap a blast furnace instrument of fine powder balling-up sex index of the maximum molecular water of a kind of simple and easy, quick, Accurate Determining iron fine powder and the data calculating of capillary water.
The technical solution of the utility model is achieved in that
1, the instrument of the maximum capillary water of mensuration is: in a water container, put a cushion block that water absorptivity is extremely strong, the hopper loader that is provided with a tubular metal is put on cushion block, the suitable for reading of hopper loader is through hole, the orifice plate back cover that the end opening of hopper loader is made with the organic glass thin plate, have the aperture that is uniformly distributed 4 millimeters, 3 millimeters intervals of diameter on orifice plate.
2, the instrument of the maximum molecular water of mensuration is: in a tubular metal sleeve, place a cylindrical foundary weight, foundary weight can free play in sleeve.
Concrete assay method:
1, measure maximum capillary water: hopper loader is coated to skim wax, in orifice plate upper berth two layers of filter paper.The dry sample mass m of weighing
1Hair (50～100g), with loose condition (of surface), to pack in hopper loader, before mensuration, at the bottom of container water level and orifice plate, maintenance is in the same horizontal line.When capillary water rises along pore, with buret, to water filling in container, keep stable level in container, until charge level is wetting, till sample no longer absorbs water, the quality m of sample after the weighing water suction
2Hair (g).According to formula: W
mMaximum capillary water=(m
2Hair-m
1Hair)/m
2Hair * 100%, calculate maximum capillary water.
2, measure maximum molecular water: the 20g sample is fully wetting to state of saturation with distilled water, static 2h.20 filter paper are placed under sleeve, and wet sample is placed on filter paper after filtration, then on sample, puts 20 filter paper well, puts foundary weight.65.5kg/cm exerts pressure
2, pressurize after 5 minutes, take out sample and be weighed as m
1Water (g), put into baking oven, in (110 ± 5) ℃, dries to constant weight m
2Water (g).According to formula: W
fMaximum molecular water=(m
1Water-m
2Water)/m
1Water * 100% calculates maximum molecular water.
3, determine balling-up sex index K=W
f/ (W
m-W
f).Wherein: W
f: maximum molecular water content %; W
m: maximum capillary water content %.
The utility model has the advantages that:: can be simple and easy, quick, the maximum molecular water of Accurate Determining iron fine powder and the data calculating of the capillary water fine powder balling-up sex index of tapping a blast furnace, pelletizing production is played to positive directive function.
The accompanying drawing explanation
Accompanying drawing 1 is measured the structural representation of maximum capillary water instrument for the utility model.
Fig. 2 is the structural representation that the utility model is measured maximum molecular water instrument.
Specific embodiment
In figure, 1. hopper loader, 2. orifice plate, 3. container, 4. cushion block, 5. sleeve, 6. foundary weight.
Put a cushion block (4) that water absorptivity is extremely strong a water container (3) is inner, the hopper loader (1) that is provided with the tubular metal of 120 millimeters of an internal diameter 25 millimeters long is put on cushion block (4), the suitable for reading of hopper loader (1) is through hole, orifice plate (2) back cover that the end opening of hopper loader (1) is made with the organic glass thin plate, have the aperture that is uniformly distributed 4 millimeters, 3 millimeters intervals of diameter on orifice plate (2); Also have the cylindrical foundary weight (6) of placing 35 millimeters of diameter 60 millimeters long in internal diameter 30 millimeters tubulose metal sleeves of 60.5 millimeters long (5), foundary weight (6) can free play in sleeve (5).
